Lesson 2 Warm-Up:
1) When the product of 2 and 3 is subtracted from the sum of 4
and 5, what is the difference?
Simplify:
2) 3105 5
3) $1.54 x 7
4) $20 - $14.79
5) 3714 + 268 + 47 + 9

Lesson 2:
Properties:
*Commutative(add)-->3 + 5 = 5 + 3
*Associative(add)-->2 + (3 + 4) = (2 + 3) + 4
*Identity (add)-->10 + 0 = 10
*Identity (mult)-->10 1 = 10
*Zero (mult)-->10 0 = 0
*Commutative (mult)-->4 5=5 4
*Associative (mult)-->2 (3 4) = (2 3) 4
